Which POTS replacement is right for your building?
🔥 Fire Alarm Panels
NFPA 72 requires a UL-listed communicator. Ooma AirDial and Lingo SafeLine Alert+ are the only UL-listed options on this list. Do not use a generic cellular gateway for a fire panel.
🛗 Elevator Emergency Phones
ASME A17.1 and ADA require a working two-way communications device. Ooma AirDial is specifically certified. Lingo SafeLine also covers this use case.
📠 Fax Machines
Fax over cellular is notoriously unreliable. Granite EPIK has the best fax support with store-and-forward technology. Alternatively, switch to eFax and retire the POTS line entirely.
🏢 Multi-Location Buildings
Granite EPIK and Cradlepoint offer centralized management portals built for portfolios. DataRemote is strong for high-density deployments with many lines per building.
